Eligibility Criteria
You may qualify if:
- Stenotic (\> 50%) or occlusive atherosclerotic disease of the distal popliteal or infrapopliteal arteries
- A maximum of two focal target lesions in one or more distal popliteal or infrapopliteal vessels
- Length of lesion is maximally 55 mm, allowing maximally 2 stents to be implanted
- Reference vessel diameter should be 2.5 mm-4 mm
- Symptomatic critical limb ischemia (Rutherford 3, 4, 5)
- Subject is able to take at least one type of thienopyridine (e.g. clopidogrel) and acetylsalicylic acid
- The patient must be \> 18 years of age
- Life-expectancy of more than 12 months
- The patient has no child bearing potential or negative serum pregnancy test within 7 days of the index procedure
- The patient must be willing and able to return to the appropriate follow-up times for the duration of the study
- The patient must provide written patient informed consent that is approved by the ethics committee
You may not qualify if:
- Patient refusing treatment
- The reference segment diameter is not suitable for available stent design.
- Unsuccessfully treated (\>30% residual stenosis) proximal inflow limiting arterial stenosis
- Untreatable lesion located at the distal outflow arteries
- More than two infrapopliteal lesions in the same limb
- Previously implanted stent(s) or PTA at the same lesion site
- Lesion location requiring kissing stent procedure
- Lesion lies within or adjacent to an aneurysm
- Inflow-limiting arterial lesions left untreated
- The patient has a known allergy to heparin, Aspirin or other anticoagulant/anti-platelet therapies or a bleeding diatheses or is unable, or unwilling, to tolerate such therapies.
- The patient takes Phenprocoumon (Marcumar).
- The patient has a history of prior life-threatening contrast media reaction.
- The patient is currently enrolled in another investigational device or drug trial.
- The patient is currently breast-feeding, pregnant or intends to become pregnant.
- The patient is mentally ill or retarded.
